An ancient biker trick,, nobody ever said it didn't work,,, stick your finger in bleach 30 minutes or less before going in. Blow dry. When you test pee on your finger into the cup. They test for parts per million and the bleach lowers the count real good. Also don't give them the first one of your day or held for more than four hours. The blood transfer is higher the longer it is inside you. A weak count might test like water and fail you. The store mix probably is best. Any one should do. Personally I never tried to fool anyone, and am not interested in working with/for lamos. Now the real truth to it is do NOT get high before you test. Hard crap is three days. If you can't stay clean three days the test is not your problem. Weed takes much more maybe thirty. If you have to quit weed what is the point..? Tell em to stuff it. You're better off in the long run. Especially if your job could get anybody injured, involuntary manslaughter is like 25 years...
Don't use bleach, they check for adulterants.
Any smoke shop or porn shop should have synthetic urine. Both Amazon and ebay sell synthetic urine. You can also buy it from spectrum labs on line.
So today I subbed some urine from a buddy who hadn't smoked in about 5 years, he smoke about a month ago (one hit) so just to make sure he was clean I bought a first check marijuana home test kit. He pissed into it and it gave a clean result, however, at this point I had to rush to the testing place (labcorp) and he could only muster up enough piss to fill my 3 oz bottle halfway so I did the only thing I thought I could do at this point and poured some of the clean urine out of the firs check home test cup into the 3 oz bottle to fill it. Will this in anyway affect the outcome of my test at labcorps, is there anything in the testing strips the could have gotten into the urine that would be detectable and raise question? This is eating away at me so all responses are welcome, knowledgable and semi-knowledgeable.. and do note that only half of the sample i submitted had been in the first check home kit cup.
